Respuesta :
The diameter of the wheel of the bicycle that covers 440m in 200 rotations is 0.7m.
What do we mean by diameter?
Any straight line segment that cuts through the center of a circle and has ends that are on the circle is considered a circle's diameter in geometry.
It is also known as the circle's longest chord.
The diameter of a sphere can be defined using either of the two methods.
The diameter or length of a circle is its circumference.
A straight line connecting a point on one end of the circle to a point on the other end, passing through the center, is the diameter.
So, the diameter of the wheel will be:
Circumference = 440/200
Circumference = 44/20
Circumference = 22/10
Circumference = 2.2/1
2πr = 2.2
Now, calculate the radius:
2πr = 2.2
r = 2.2/2π
r = 7/22 * 2.2/2
r = 0.35
Diameter: 3.5 * 2 = 0.7m
Therefore, the diameter of the wheel of the bicycle that covers 440m in 200 rotations is 0.7m.
